Turku Arabic or simply just Turku is an extinct variant of Bimbashi Arabic that served as a lingua franca in Chad.[1] It's the ancestor to Bongor Arabic[2] and potentially other Arabic pidgins spoken in Chad today, but since they have not been described, it is unclear whether they are direct descendants of Turku.[3]
